Linguistic difficulties, some peculiarities of the translation of stylistic devices from English into Russian and vice versa in the journalistic sphere
Knowledge of foreign languages, especially English as an international one,
broadens working horizons, gives a possibility to communicate with people all
over the world without an interpreter and it helps to save time, which is so pre-
cious today. Moreover, this knowledge makes it possible to use a great number
of information sources & better understand the peculiarities of foreign press
DEPENDENCE OF THE VISCOSITY COEFFICIENT OF THE NIOSOMAL DISPERSION ON THE TEMPERATURE AND PARTICLE SIZE OF THE DISPERSED PHASE
The aim of this study was to experimentally investigate the dependence of viscosity coefficient of niosomal dispersion based on PEG-12 Dimethicone on the temperature and size of niosomes vesicles. The experiments were carried out with niosomes, the average size of which varied from 85 to 125 nm. The temperature varied from 20 to 60 °C, the volume concentration varied from 1 to 10 %. The particle size was determined by scanning electron microscopy (SEM) with subsequent statistical data processing. This study showed that the viscosity of niosomal dispersions significantly depends on both the temperature and the size of niosomes vesicles. With increasing temperature, the viscosity of niosomal dispersions decreases and with increasing particle size, the viscosity increases
Investigation of the frequency characteristics of composite iron powders with insulating oxide coatings
This article discusses methods for studying the frequency characteristics of composite iron powders with insulating oxide coatings. The main dependences of hysteresis losses on induction for a full cycle at a frequency of magnetization reversal for various cross-sections of iron powders, sharply differing in the shape of the hysteresis curve and the values of the main magnetic characteristics, are studied, and also frequency dependences in the range of 50 Hz - 1 MHz of the figure of merit and inductance for samples based on composites are considered from powder Hoganes ASC100.29 after annealing in air, in water vapor and hydrogen at a temperature of 400 ° С for two hours. Based on the analysis of the dependencies, it can be explained by the fact that a material with a thin layer has a lower electrical resistivity, which means that the total electromagnetic losses will also be greater due to an increase in the contribution of losses to eddy currents. At the same time, the magnetic permeability at a frequency of 1 kHz differs by 30 units, and with an increase in the frequency to 1 MHz, it decreases by 10-15% for both materials. This makes it possible to use iron-based soft magnetic materials for electrical engineering
